Patent

CA 2273210

The invention concerns a class D amplifier in which a high-frequency reference signal (E) is pulse width modulated by an input signal, such as an audio signal, and in which there are generated a pair of bipolar pulse drive signals (I, J), comprising an error generator which forms a signal with an average value which corresponds to the DC component of the pulse drive signals, and which is fed back to the pulse width modulator for the adjustment of the modulator. The high- frequency reference signal (E) is generated from a first clock signal (A), and the individual pulses of the respective pulse drive signals are controlled via a second clock signal (C) which is derived from the first clock signal (A).

L'invention concerne un amplificateur de catégorie D dans lequel un signal (E) de référence haute fréquence est modulé en largeur d'impulsion par un signal d'entrée, tel qu'un signal audio, et dans lequel est générée une paire de signaux bipolaires (I, J) de commande d'impulsion, comprenant un générateur d'erreur qui génère un signal dont une valeur moyenne correspond à la composante de courant continu des signaux de commande d'impulsion et qui réalimente le modulateur de largeur d'impulsion afin de régler ledit modulateur. Le signal (E) de référence haute fréquence est généré depuis un premier signal d'horloge (A) et les impulsions individuelles des signaux respectifs de commande d'impulsion sont commandées par l'intermédiaire d'un deuxième signal d'horloge (C) dérivé du premier signal d'horloge (A).
